Automotive Catalog Single 3-Input Positive OR-AND Gate

This device is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC1G3208-Q1 is a single 3-input positive OR-AND gate. It performs the Boolean function Y = (A + B) ⋅ C in positive logic.

By tying one input to GND or VCC, the SN74LVC1G3208-Q1 offers two more functions. When C is tied to VCC, this device performs as a 2-input OR gate (Y = A + B). When A is tied to GND, the device works as a 2-input AND gate (Y = B ⋅ C). This device also works as a 2-input AND gate when B is tied to GND (Y = A ⋅ C).

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
